LTCC based patch antenna for biomedical applications at ISM band

An electrically small, LTCC based slotted patch antenna is designed and simulated at industrial, scientific, and medical (ISM) band (902-928 MHz). The proposed antenna has a size of 25×25×1.5 mm
³
and it is loaded with superstrate and shorting posts. The designed antenna was simulated on a skin-model as well as in free-space. The skin-loaded antenna resonates around 915 MHz with a peak realized gain of -2.1dB and has a BW of 15% around its center frequency.
